Description
Technical field
The present invention relates to heat recovery coke oven technical field more particularly to a kind of furnace retaining ironwares of heat recovery coke oven.
Background technique
The furnace retaining ironware of traditional heat recovery coke oven is by groups such as upper furnace door, lower furnace door, protection board, furnace retaining frame, tie rod, furnace stays
At.As shown in Figure 1, wherein protection board is divided into protection board 2, middle protection board 3 and lower protection board 4 again, three kinds of protection boards are by setting
Set bolt between seam and pressing plate 7 adjust height and forms a plane, the plane that each protection board is formed with it is corresponding on
It is connected in the form of sealing firmly between fire door, lower furnace door.Since the size and weight of each protection board are larger, installation process is not
Evitable there are errors, in addition the influence of coke oven production process high temperature, is total to by upper protection board, middle protection board and lower protection board
Often not can guarantee with sealing surface its levelness formed, and the sealing effect sealed firmly is poor, cause protection board and upper furnace door,
Effective sealing can not be formed between lower furnace door.
The fire door of heat recovery coke oven is generally divided into upper furnace door and lower furnace door, and upper furnace door is seldom opened after being installed in place, and
In coke oven normal productive process, coalings every time and require to open lower furnace door before coke pushing.Therefore lower furnace door and its sealing surface it
Between leakproofness just seem particularly significant.If sealed between lower furnace door and corresponding protection board and lower furnace door and upper furnace door bad
If, will lead to air by the gap on sealing surface and enter carbonization chamber, air enter after carbonization chamber with coke and raw coke oven gas
Burning, is easy to cause coke burning, and not only the yield of STRENGTH ON COKE impacts, but also local temperature is excessively high is also easy to burn out furnace
Door.
Summary of the invention
The present invention provides a kind of furnace retaining ironwares of heat recovery coke oven, are needing through individually setting on the outside of normally open lower furnace door
Lower furnace door frame is set, form integral sealing face between lower furnace door frame and corresponding protection board and upper furnace door and is connected using flexible sealing,
To substantially improve the integral sealing effect of heat recovery coke oven furnace retaining ironware.
In order to achieve the above object, the present invention is implemented with the following technical solutions:
A kind of furnace retaining ironware of heat recovery coke oven, including upper furnace door, lower furnace door, upper protection board, middle protection board and lower protection
Plate sets protection board on the outside of upper furnace door, and the two sides of lower furnace door set middle protection board, set protection board on the downside of lower furnace door；It is described
Furnace retaining ironware further includes lower furnace door frame；The lower furnace door frame is set to the outside of lower furnace door, and lower furnace door frame passes through circumferentially arranged
Multiple gib headed bolts are fixedly connected with upper furnace door, middle protection board, lower protection board respectively；Between middle protection board and lower furnace door frame, under
Flexible sealing connection is respectively adopted between protection board and lower furnace door frame, between upper furnace door and lower furnace door frame, the hook of lower furnace door is set
It sets on lower furnace door frame.
The lower furnace door frame is the rectangular frame structure matched with lower furnace door, by top frame, side edge frame and bottom
Portion's frame composition.
The top frame of the lower furnace door frame extends to the bottom inside of upper furnace door, the lateral surface edge edge of top frame
Horizontal direction opens up groove, fills refractory ceramic fiber rope in groove, realizes between lower furnace door frame and upper furnace door matching surface
Flexible sealing.
2 side edge frames of the lower furnace door frame extend respectively to the outside of middle protection board, the medial surface side of side edge frame
Groove is opened up at edge along the vertical direction, refractory ceramic fiber rope is filled in groove, realizes lower furnace door frame and middle protection board cooperation table
Flexible sealing between face.
The bottom frame of the lower furnace door frame extends to the top outer of lower protection board, the medial surface edge of bottom frame
Open up groove in the horizontal direction, refractory ceramic fiber rope filled in groove, realize lower furnace door frame and lower protection board matching surface it
Between flexible sealing.
Compared with prior art, the beneficial effects of the present invention are:
1) present invention improves on the basis of existing heat recovery coke oven furnace retaining ironware, increases on the outside of lower furnace door
Lower furnace door frame can be avoided effectively caused by faying face injustice between each protection board compared with traditional heat recovery coke oven
The bad disadvantage of sealing effect guarantees the stabilization of coke oven production process, extends the service life of fire door；
2) it in traditional heat recovery coke oven, is fixedly connected by way of bolt clip plate between each protection board, this connection shape
Formula not can guarantee the globality between each protection board；And in the present invention, lower furnace door frame by gib headed bolt and corresponding protection board it
Between be connected and fixed, can make between protection board and lower furnace door frame formed an entirety, effectively increase between furnace retaining ironware
Globality avoids impact when dislodging fire door from impacting the connective stability between each furnace retaining ironware；
3) in traditional heat recovery coke oven, upper furnace door is not turned on during normal production, is suspended on the carrying roller of protection board, is passed through
Gravity makes to form sealing between upper furnace door and upper protection board, while making to form sealing between upper furnace door bottom and lower furnace door；Under and
Generated impact force has a significant impact for the leakproofness of upper furnace door when fire door dislodging；The present invention by adding lower furnace door frame,
Effectively improve disadvantages mentioned above, upper furnace door not only passes through carrying roller and is fixedly connected with upper protection board, but also by gib headed bolt with
Lower furnace door frame connection, so that furnace retaining ironware be made to form an entirety；Meanwhile upper furnace door is no longer connecing with lower furnace door during normal production
Touching, thus influence when efficiently avoiding dislodging lower furnace door for upper furnace door leakproofness.
